Definitions

  • the invention relates to a harvesting header for maize harvest, with a movable in a forward direction over a field frame on which one or more laterally juxtaposed harvesting device (s) for harvesting maize plants and downstream of the harvesting device (s) arranged mulching with actively driven elements for processing the plant stumps remaining in the ground after harvesting are mounted, which are supported with respect to the frame so as to be movable in height and following the floor contour, runners arranged below the elements.
  • the DE 35 15 295 A1 shows a corn picker with a number of side by side arranged row units and such a mulcher, which extends over the entire width of the corn picker and the row units associated, attached to a drivable horizontal shaft mounted knife.
  • the shaft is arranged within a housing, which is hinged on the front side about an axis parallel to the shaft pivotally on the frame of the corn picker and is supported by skids on the ground. The areas of the skids coming into contact with the ground lie exactly below the axis of rotation of the shaft.
  • the DE 39 34 862 A1 shows a similar stalk shredder on a corn picker, however, the serving for crushing the crop residue knives rotate about vertical axes and are driven by propeller shafts or hydraulic motors.
  • a mowing attachment for harvesting whole maize plants is shown, on the underside of which side by side mulching devices are mounted with knives rotating around the vertical axis.
  • the mulchers are mounted height-adjustable on the mowing attachment by means of parallelogram links and are supported below the axes of rotation of the blades by skids on the ground.
  • DE 39 34 862 A1 and DE 10 2004 020 447 A1 each extend over the entire width of the maize harvesting device and move together up and down when run over them supporting and defining their vertical position runners bumps.
  • the stubble standing there is processed only at a relatively high altitude above the ground.
  • the knives may reach into this rise, which leads to premature wear or damage of the knife.
  • the St Sknicker the DE 10 2013 000 438 B3 Although individual follow the respective floor contour, but no actively driven elements are provided.
  • the object underlying the invention is seen to provide a harvest header for corn crop, in which the mentioned disadvantages are not present or to a lesser extent.
  • a corn harvesting header comprises a frame movable in a forward direction across a field, on which one or more laterally juxtaposed harvester (s) for harvesting maize plants and mulching devices located downstream of the harvesting device (s) having actively drivable elements for crushing, fumigating or otherwise destructive processing of plant stumps remaining after harvesting in the soil are mounted, which are supported with respect to the frame height-movable and following on the ground contour, below the elements arranged runners, ie deeper than the elements are positioned.
  • the mulching devices are mounted separately movable in height on the frame.
  • the mulching means may be hinged separately from each other about the transversely to the forward direction of the header and horizontally extending axes pivotally mounted on the frame. It would also be conceivable to store them in a vertical direction displaceable.
  • the elements may be drivable about an axis of rotation oriented horizontally and transversely to the forward direction or about an axis of rotation inclined obliquely forwards and downwards.
  • the skids of the mulching devices may each be biased by a spring and / or gravity in the direction of the ground.
  • the mulching device can be supported relative to the harvesting device in the lateral direction movable on the frame and guided by guide means along the plant stumps.
  • the mulching device is not mounted immovably in the lateral direction on the frame of the header, but is laterally displaced by guide means and guided along the plant stumps. This ensures that the plant stumps can be safely processed by the mulching device, even if their working width is smaller than that of the harvesting device. This advantage is also achieved when the working widths of mulcher and harvesting device are the same, because even then, for example when driving on curves ensures that all harvested plant stumps are processed by the mulching.
  • the guide means mechanically interact with the plant stumps.
  • the guide means may interact with the plant stumps upstream or downstream of the mulching means.
  • the guide means comprise runners guided on the ground or immediately above the ground, which are movable in the lateral direction through the plant stumps.
  • the guide means may be mechanically coupled to the mulching device.
  • a sensor may detect the position of the guide means and be connected to a controller which controls an actuator for lateral adjustment of the mulching device.
  • the guide means can detect the plant stumps without contact, for example by means of a light barrier or a camera or an ultrasound sensor, and an actuator controlled by the detection of plant stumps automatically adjust the mulching device.
  • the header can be designed in the form of a corn picker or header for harvesting whole corn plants.
  • a self-propelled harvester 10 such as a forage harvester, is constructed on a chassis 12 carried by powered front wheels 14 and steerable rear wheels 16 and moved across a field in harvesting operation in a forward direction V.
  • the operation of the harvesting machine 10 is carried out by a driver's cab 18, from which a header 20 is visible.
  • a header 20 picked up from the ground Good, z.
  • corn or sunflowers is fed to the harvesting operation by arranged in a feed housing 36 pre-press rollers 30, 32 of a chopper drum 22, which chops it in cooperation with a counter-blade 46 into small pieces and gives it a Nachbelixer 24.
  • the knives of the chopper drum 22 can be sharpened by a grinder 42 as needed.
  • a Nachzerklein fürsvortechnisch with rollers 28, 28 ' Between the chopper drum 22 and the conveyor 24 extends (at the harvest of corn) a Nachzerklein réellesvoriques with rollers 28, 28 ', through which Good to be conveyed to the post-accelerator 24 is fed tangentially.
  • the header 20 is used to harvest whole corn plants 118 (s. FIG. 3 ) And includes a number of laterally juxtaposed harvesting devices in the form of mowing and collection devices 72 with about vertical axes rotating, stacked conveyor discs and arranged below cutting discs around the edge distributed recesses for transporting the plants, as for example in the EP 0 760 200 A1 to be discribed.
  • the mowing and collection devices are by gear housing 76 at a frame 84 of the header 20 supported.
  • a plurality of mulching devices 60 each associated with a mowing and drawing-in device 72, are arranged laterally next to one another, which serve to comminute the plant stumps 74 remaining on the corn plants after harvesting, in particular to destroy the overwintering area of the corn borer.
  • the mulching devices 60 comprise as elements 66 for processing the plant stumps 74 about a central shaft 78 (s. FIG. 2 ) distributed shaft 70 is oriented horizontally and transversely to the forward direction and is driven by a hydraulic motor 80.
  • the shaft 78 extends between two arms 62 and is rotatably supported thereon.
  • the arms 62 extend forwardly from the shaft 78 to a bearing 68 at which the arms 62 are pivotally mounted on a cross member 82 freely about the transverse axis.
  • the cross member 82 in turn is pivotally mounted centrally about a vertical axis 86 on the frame 84, e.g. on the gear housing 76 or an associated support member.

  • the knives 66 are angled approximately at half the length by about 45 ° outwards in the axial direction. On a console 88 two knives 66 are attached in pairs, which are angled in opposite directions.
  • the mulching devices 60 of which one or more of the one or more mowing and intake devices 72 may be associated and mounted in the transverse direction of the header 20 where the maize plants 118 run into normal operation, according to the trimming the plants 118 through the mowing and collection devices 72 in the soil remaining plant stumps 74.
  • the runners 64 are located with respect to the forward direction V just below the axis of rotation of the shaft 78 on the ground and define the angle of the arms 62 around the bearing 68. The runners 64 leave between them a gap 92 through which the plant stumps 74 can pass through the header 20 is moved across the field.
  • the plant stumps 74 are defined by the elements 66 of the mulching device 60, ie the knives 70, crushed or shredded.
  • the mulching device 60 easily follows the contour of the ground, even if the ground should have waves in the forward direction. Due to the separate suspension of all mulching devices 60 it is achieved that all mulching devices 60 follow the contour of the ground exactly even when the ground has waves in the transverse direction.
  • the runners 64, between which the plant stumps 74 run, also direct the mulching device in the lateral direction and thus serve as guiding means, which guides the mulching device 60 along the plant stumps 74.
  • the plant stumps 74 would turn the runners 64 and thus the entire mulching device 60 about the axis 86 and therefor ensure that the plant stumps 74 are still gripped and shredded by the mulching device 60.
  • the skids 64 could be backward of the axis of rotation of the shaft 78 in ground contact, instead of just below. For this, let the disclosure of the DE 10 2016 212 621 A1 referred to by reference in these documents. Also, an active lateral adjustment of the mulcher 60 could be made to follow the plant rows as described in the just mentioned document.
  • FIGS. 3 and 4 show a second embodiment of a header 20, in the forward direction V at the front of the harvester 10 of the FIG. 1 can be attached.
  • the header 20 in the illustrated embodiment is a per se known corn mower attachment which may include a center portion and two side panels (with respect to the forward direction of the harvester 10) disposed laterally to the left and right of the center portion.
  • the side panels are mounted for road transport pivotally upwards on the central part and can be hydraulically swung down to the harvesting operation, so that they run parallel to the central part during harvesting operation. Then they can be swung back up.
  • the harvesting attachment 20 is equipped in a manner known per se with the mowing and intake devices 72, divider tips 94 and cover plates and conveying means in order to feed the harvested crop to the chopper drum 22 of the harvesting machine 10.
  • the harvesting attachment 20 pulls up the stalks of the crop 118 in an upright position, cuts them off and feeds them to the intake housing 36 and then to the chopper drum 22 of the harvesting machine 10.
  • the header 20 includes the frame 84 which includes a cross member extending down the rear of the header 20, which is composed of three segments, one of which is disposed on the middle portion 38 and one on each side portion 40.
  • the gear housing 76 are screwed, which serve to drive a mowing and retraction device 72.
  • a drive shaft 96 for driving the mowing and intake devices 72 in the Gearboxes 76 arranged gear, which also serves to drive the other funding of the header 20 and is driven by an output shaft of the harvester 10 extends laterally within the hollow lower cross member.
  • FIG. 3 shows the harvesting attachment 20 in a position that it takes during harvesting, for which the feeder housing 36 by an actuator (not shown) about the axis of rotation of the cutterhead 22 from the in FIG. 1 lowered position shown.
  • This actuator also controls the height of the header 20 above the ground, in a per se known sensor-based manner.
  • a mulching device 60 is mounted at the rear of each mowing and intake device 72.
  • the mulching device 60 is arranged with its axis of rotation in the lateral direction at the rear of the axis of rotation of the associated mowing and intake device 72. There, the plants enter the normal harvesting operation. If a mowing and intake device 72 harvested several rows of plants, it can be assigned to several mulchers 60 whose axes of rotation are arranged at the rear of the expected inlet points of the rows of plants. It would also be conceivable to distribute the shredders 60 gapless or with small gaps over the entire working width of the header 20.
  • the mulcher 60 comprises two diametrically opposed elements 66 for processing the plant stumps 74, which are rigidly connected to a central shaft 78 via radial arms 98. Instead of rigid arms 98, the elements 66 for processing the plant stumps 74 could also be connected to the shaft 78 by chains or other flexible elements.
  • the elements 66 for processing the plant stumps 74 are designed as a blunt impact body, ie shaped spherical or cigar shaped.

  • the drive shaft 96 extends and is positively coupled to the hexagonal hollow shaft 102.
  • the transmission 100 includes drive elements (not shown) which drive the hollow shaft 102 to the shaft 78, such as bevel gears.
  • the transmission 100 is freely pivotable relative to the drive shaft 96 and the lower cross member of the frame 84 about the axis of the drive shaft 96.
  • a gear 100 enclosing the gear 100 from both sides is rigidly connected to the lower cross member of the frame 84.
  • a lower, the two sides of the gear 100 adjacent plates of the console 104 connecting plate is connected at its bottom with a stop member 106 which serves in cooperation with a cover plate 108, the range of movement of the shaft 78 and thus the elements 66 for processing the plant stumps 74 and collisions with other parts of the header 20 to avoid.

  • the hollow shaft 110 is freely pivotable with the gear 100 and the shaft 78 relative to the lower cross member of the frame 84 about the longitudinal axis of the drive shaft 96.
  • the hollow axle 110 carries a flange 112, to which a holder 114 is attached.
  • the holder 114 is rigidly connected to the cover plate 108.
  • the cover plate 108 extends across the width of the mulching device 60 and is slightly wider than the diameter of the enveloping circle described by the elements 66.
  • the cover plate 108 extends in the forward direction V from the center of the hollow shaft 110 and from there obliquely backwards and downwards to a rear runner 64, which rests on the ground.
  • a (compression) spring 116 is connected between the support frame 84 of the header 20 and the cover plate 108 and pushes the cover plate 108 down.
  • the runner 64 relative to the cover plate 108 may be adjustable to the elements 66 for processing the plant stumps 74 in their rearward position at a level bottom further down pose as on uneven ground.
